Best things i can Do to improve power....without a swap??? Options

[KB-2]

okay.
so im looking to just make it slightly quicker
i know of an intake......adn thats about all i know

anything else cheap that willl do anything?

[celica47]

Bro this has been covered a couple times, anything less turboing is waste of money honestly. Celicas engines dont take to bolt ons that well.

[Bitter]

run 89 or 93 octane and advance your timing to 12-15 degrees. http://www.toyotacelicaonline.com/timing.htm
ebay header could help, more so if it eliminates the precat.
exhaust could help some, but probably not for the cost.

Take off everything out of your car to the point where it's just you, the seat, the wheel, the chassis, and the engine. Weight reduction FTW!

[celica47]

Then take un needed engine parts out.

Get rid of the balance shaft

[puretone]

Get rid of the balance shaft

while you are at it, get rid of some pistons too, unnecesary weight and all....less rotational mass

[MaskedMan]

yeah you only need 3 pistons anyways like a geo metro. or you could go old school BMW isetta style and go 1 piston. the choice is yours. and make sure that you change your pistons to carbon fiber.

Ok but seriously. If you want to gain a little power without a swap, then you can just turbo your current engine and run low boost. Or nitruos at about 25-50 shot.

Nothing cheap will do anything noticable.

Whatever, you totally dont need it. Its just there to reduce vibration and honestly the difference without it is nill. No harm to the engine and a definite inprovement in performance. I know a guy who builds the 5S for race setups and thats the first thing he does.

[celi_gt_racer]

more info? you know someone who builds 5s's for race apps??? what else does he do? details details! how does he remove the balance shaft?? is there a kit you would need, or a pulley

I can get more info if you guys want. I know the 4G guys have been doing this for years. I would imagine it's good for freeing up at least 6 to 8HP, considering the displacement size of the 5S.

nitrous is your best bet !!!

[pandakid]

does those apex-i AFC works?

[Bitter]

yes, an AFC can make a difference, but probably not earth shattering.

[hitcachi]

yes, an AFC can make a difference, but probably not earth shattering.

You really shouldnt get one or use one unless you really know what your doing, otherwise your going to cause yourseld alot of problems. And if this guy is asking this question, im probably going to recommend that he not get one.

A good, quality nitrous setup is perfect for somone who wants power on a budget. I think ZEX makes a nice dry kit for like $450, which isn't bad at all.

everyone alwasy says that, but i have never seen a nitrous setup of a 4cyl econo motor last more then a few months of joy rides. a dry kit would definelty lead to engine damage, imho.

I believe the general rule of thumb for safe nitrous is using one step colder spark plugs and retarding the timing by 3 degrees. Guys I know on Hondaswap and Hondatech have been doing it safely for years. 50 extra hp on the 5SFE would be really nice, especially for $500.

Actually I know quite a few people who have had great success with them. I had one '92 Corolla with a 4AFE in my shop a while back, he had been running a ZEX dry kit for like two years when he blew the auto tranny. After getting a swap, he sold the engine and it's running on another car to this day (as far as I know). As mentioned, it's important to follow the ZEX instructions, which say to use colder spark plugs and retard the timing. This is very important.

Also many people, obviously including you, don't understand how a dry kit works. They think that it injects N20 without compensating with fuel at all. However, that's not correct. A dry kit add fuel by increasing the fuel pressure when the N20 is being injected. A wet kit, which taps into your fuel system and injects fuel into the intake with the N20, should NEVER be used on an EFI car. The reason is that the intake manifold on an EFI car is designed to flow ONLY air, which has different flow properties than fuel. Using a wet kit on a car with and EFI-designed intake manifold will result in one cylinder being very rich and another being very lean. That type of kit is for carburated vehicles. However, a dry kit is only safe to a certain level, usually a 50-shot on a 4-cylinder engine. Beyond that, you would want to go with a direct-port kit which injects both N20 AND fuel at the PORT LEVEL, so each cylinder gets the right mixture. That's the best, and most expensive, setup that you can buy.

Also you can tune N20 injection with some piggybacks and most standalones, which is even more ideal.
